Dirt Rally stuttering on PS4 PRO, unplayable!

Here is a video of what is going on, i played yesterday and it was fine, i tried to play today and this is whats happening, i reinstalled the game and it is the same, i turned boost mode on/off on ps4 pro, same issue, its disc version, disc is like new, any fix for this, i cant play it anymore and all the other games work fine.Even if i start application without update it still stutters...

As far as I recall, last fall PS4 in general got a HDR patch, and Pro also has upscaling 4K I suppose.

I saw a remark on Eurogamer how games could activate boost mode, and if they got problem with game they could turn it off. So my understanding is that this is not validated by Sony at all for a specific game or anything special about boost, either games work at higher clock or not - it seems.

I think PS4 boost just about correspond to how Xbox One S has higher clock than launch version. Maybe increased framrate of 5-10 fps or so. Was a demo on eurogamer.
